TO ALL WHOM IT MAY CONCERN:

Be it known that I, A. C. CORPE, of Sta'ord, in the county of Tolland,and State of Connecticut, have invented a new and improved Machine forStretching Cloth; 'and that the following specification, taken inconnection with the accompanying drawings,- hereinafter-refcrred to,forms aiull and exact description of thesame, wherein I have set forththe nature and ,principles of my said improvements, byA which vmyinvention may be distinguished from all others of a similar class,together with such parts asvI claim, and desire to have secured to me byLetters Patent.

f Ths invention relates `to a new and improved machine for stretchingcloth, with aview of rendering the same smooth, and unfolding suchportion of the selvedges which may have been rolled over -in themanipulations to which it-was subjected after being taken from the'loom.l v

The invention consists of two horizontal gear-clamps and rollers, allplaced in a suitable frame, and arranged to operate as hereinafter setforth. In the accompanying sheet of drawings- Figure 1 is a plan or topview of my invention. VFigure 2 a vertical section of the same, takeninthe line my, iig. 1.

Similar letters of reference indicate like parts.

A'represents a frame, which may be constructed in any proper manner-'tosupport the working parts, and B B represent two'horizontal gear-clamps,each of which is composed of two gear-wheels,l a a', placed, onedirectly over the other. The lower wheels a are perfectly horizontal,their axes b being vertical, and fitted loosely in guides or bearings cattached to a cross-bar, d, of the frame A. The upper gear-wheels a ofthe clamps are slightly inclined from ahorizontal plane, their outermostparts being rather nearer Ythe faces or 'upper surfaces of the lowerwheels a than their inner parts, as shown in iig. 2. This position ofthe upper wheels a is obtained by having their axes e fitted inbearingsf, which are placed in upright sockets g on a cross-har, h ofthe frame A, the bearings having a certain degree of adjustability in alateral direction in the sockets, and held in place by set-screws z',which pass through thesockets, as v vill be fully understood byreferringto gf2. By this arrangement it will be seen that the cloth, shown inred,which is drawn between the wheels a af of the clamps,

`will be clutched or griped between the outer parts of said wheels. Thecloth passes from between these wheels over a roller, C, in the frame A,andis wound upon a roller, D, in the upper part of a frame, E, the lowerend of which is fitted loosely upon a shaft, j, at the lower part ofthefranie A. rlfhs roller D is rotated through the medium of gearingfrom a. shaft, z', at one side of the frame E, motion being communicatedto it from a driving-pulley, through themedium of gearing n and aclutch, o, `the latter being operated by a lever, p, so as to connectthe gearing'n with the driving-pulley m, or disconnectit therefrom, asmay bedesired. The upper and'lower wheels a a. of the gearelamps B Bgear into pinions'q g on barrels F, on the upper ends of which there arealso bevel-pinions r, which gear into bevel-teeth s 'at the inner sidesof wheels t, which are toothed at their peripheries. d C. The barrels -Fwork loosely on upright xed axes v on the frame A, and on the upper endsof the axes e of, the upper 'wheels a of the gear-clamps there aresecured circular heads w, against the under sides ofI which:

eccentrics a. bear, which eccentrics are to raise the upper wheels a.These eccentrics have levers bx attached for the convenience ofoperating them. j y u i From the above description it will be seen that,when the roller D is turned, the cloth will be drawn between thegear-clamps B B, the latteiturning simultaneously, and with the samemotion, as they are both connected with the roller C, and thesegear-clamps will stretch the elth laterally and unrollthe selvedgeswherever turned over, Inadjusting the cloth between the upper and lowerwheels of thegear-clamps, at the commencement of the operation, theupper wheels a are raised by adjusting the eccentrics a,and, when thecloth is secured to roller D, the upper wheels are lowered, so as tobear upon the cloth. v

Having thus described my invention, I claim as new, andd desire tosecure by LettersP-atent- 1. The two gear-clamps B B, composed each oftwo wheels, a a', one placed above the other, and the upper wheelsarranged so as to be capable of adjustment both vertically andlaterally, substantially as shown and described.

2. I claim the arrangement of gearing as shown, in connection with thegear-clamps B B and'roller C, vwhereby an equal movement of the clampsis insured, substantially as shown and described.

3. The supplemental frame E, provided with the roller D, upon which thecloth is wound, in connection with the gearing k u, clutch o,driving-pulley m, and shaft l, all arranged substantially as shown anddescribed. The above specification of my `invention signed by me, this23d day of April, 1867. j
